37 | The C<matcher:select> action enables a mode in which it is possible to |
|
|
38 | iterate over the matches using the keyboard and either activate them |
|
|
39 | or copy them to the clipboard. While the mode is active, normal terminal |
|
|
40 | input/output is suspended and the following bindings are recognized: |
|
|
41 | |
|
|
42 | =over |
|
|
43 | |
|
|
44 | =item C<Up> |
|
|
45 | |
|
|
46 | Search for a match upwards. |
|
|
47 | |
|
|
48 | =item C<Down> |
|
|
49 | |
|
|
50 | Search for a match downwards. |
|
|
51 | |
|
|
52 | =item C<Home> |
|
|
53 | |
|
|
54 | Jump to the topmost match. |
|

55 | |
|
|
56 | =item C<End> |
|

|
|
61 | |
|
|
62 | Leave the mode and return to the point where search was started. |
|
|
63 | |
|
|
64 | =item C<Enter> |
|
|
65 | |
|
|
66 | Activate the current match. |
|
|
67 | |
|
|
68 | =item C<y> |
|
|

74 | It is also possible to cycle through the matches using a key |
